Almost passed out! What's wrong? What do I do?

So I'm bulimic. I know it's not good and I don't care so please don't tell me anything like that. So basically I was binging and purging 3+ times a day nonstop for the last week and a half. a moment ago my vision blurred and I almost passed out. Currently I'm sitting on the floor in my bathroom with my face and throat hurting like hell. What do I do to stop being so dizzy and also get my face to stop hurting. Please don't say stop bingeing and purging because I can't do that. Thanks.
